850R Recloser/Switch ControllerFast 4 shot auto reclose for greater grid reliability
An integrated SolutionThe need to equip distribution networks with devices and software to meet the challenges of distributed generation and increased demand is global. GE has accepted this challenge on behalf of its customers, and is leading the way with products that are more intelligent , simpler to deploy and more effective in addressing the demands of the new network.
The 850R provides high speed distribution automation integrating easily into new or existing networks, enabling more reliable and efficient distribution systems.

850R Recloser ControllerThe 850R contains a unique universal driving electronics module that has been developed to match with most recloser* device. This design provides reliable 4 shot auto reclosing.
Supported modes of operation include:
• 3 phase trip, 3 phase lockout
• 1 phase trip, 3 phase lockout
• 1 phase trip, 1 phase lockout
With a 2ms protection pass, the 850R relay provides faster response to current, voltage, power, and frequency protection elements; helping reduce stress on assets.
The 850R provides the flexibility to assign the relay current (CT) and voltage (VT) terminal configuration to match the primary recloser and utilities terminal configuration ensuring that the right phase is always read by the controller irrespective of how the main line were transposed.
In case if distribution feeder has only one VT/voltage source (to measure single phase to neutral voltage or phase-to-phase voltage), the 850R facilitates 3-phase power and energy measurements by deriving pseudo 3-phase voltage from any one VT source connected by assuming a balanced 3-phase system.
The 850R supports redundant Ethernet and fiber port physical interface options and a wide range of industry standard protocols for communication, namely Modbus TCP/IP, DNP 3.0, IEC 60870-5-101, IEC 60870-5-103, IEC 60870-5-104, IEC 61850 Ed2, IEC 62439 / PRP/HSR; facilitating easy integration into new or existing SCADA/DCS networks.
The 850R comes with an integrated universal driving electronics that is capable of driving the Open/Close mechanism of practically any make of reclosers.
Integrated ControllerThe 850R has a built in Integrated Recloser controller that comperises the Driving electronics, the UPS switching mechanism, the Battery management system & the capacitor charing system. This integrated system ensure a smoother coordination between the various process that are critical to the flawless operation of the controller.
Supply SwitchoverThe Supply Switchover function allows the main DC power source to change to battery power in case of a main DC power loss. When the relay is operating on battery power, the system is limited based on a userdefined maximum time or minimum battery voltage level, to avoid overdischarge of the battery. When the minimum battery voltage level is reached or the set time has expired, the 850R relay and any accessories supplied by battery power go into sleep mode (instant shutdown). To Awaken (restart) the relay from sleep mode, press the front panel wakeup button.
Embedded Cyber Security and Communications The 8 Series delivers a host of cyber security features that help operators to comply with NERC CIP guidelines and regulations.
Wi-Fi Connectivity• Simplify set-up and configuration
• Simplify diagnostic retrieval
• Allows personnel to be a safer distance from the front of the switchgear
• WPA-2 security
Distribution AutomationFrom simple automation to advanced analytics, the 850R provides the flexibility and scalability required to meet unique application requirements for the distribution utilities.
Distributed FDIRThe 850R supports peer to peer communication via IEC 61850 GOOSE that can achieve a distributed FDIR scheme. Unlike other vendors, the 850R can communicate with any controller as long as it supports IEC 61850 GOOSE.
Decentralized FDIRWith the G500 Advanced Substation Gateway communicating with the 850R controller out in the field, a system defined decentralized FDIR scheme can be designed with the decision making algorithm residing at the substation level rather than the DMS level. Multiple functionalities like the Gateway functionality, Substation Automation, Station HMI & Distribution Automation can be combined into one G500 bringing in more visibility & local control.
The G500 can also send the received data to the DMS/ADMS for supervisory monitoring and control in a more efficient manner. Automation applications, such as IVVC, can also be added at the substation level.
Monitoring and Data InputThe 850R delivers accurate data to centralized and decentralized applications enabling advanced analytics. This distributed fault data analysis enables FDIR/ FLISR schemes to deliver optimal network reconfiguration in varying neutral treatments, such as direct or high impedance grounding.

Protection & ControlThe 850R provides secure and reliable protection by offering a comprehensive range of standard and advanced elements with multiple-stages and wide setting ranges for each. The controller provides directional and non-directional overcurrent protection along with the option of single-phase tripping and reclosing, to limit system impact and improve reliability synchronism check function ensures that the voltages are within safe limits before allowing closing and auto-reclose operations. Additionally, voltage and frequency protection elements may be used to disconnect DERs connected to the feeder. The 850R includes six voltage inputs to monitor voltages on both Load & Line sides of the recloser thereby delivering a safer level of performance especially for Bus Tie applications.

Reliability Enhancements
Autoreclose (1 Pole / 3 Pole)The Autoreclose function provides greater flexibility to allow its applicability to many different utility control practices, for example:
Up to 4 reclosing shots with separate programable “dead times” per shot.
850R allows 4 programmable flexcurves that can be initialized by any IEEE/IEC curves or from 41 built-in recloser curves. This enables smoother coordination between Upstream & downstream devices
Third flexible is initiating AR function from any of the multiple overcurrent functions, or derived from the flex logic or even external source (i.e. contact input or GOOSE).
The 850R provides adaptive functionality to reduced system stress. This is achieved by blocking overcurrent functions or raising its pickup level. It also facilitate supervision functionality by monitoring number of reclose shots per hour in order to alarm or lockout the condition.
Adaptive approach allows increase in pickup level per shot and reducing time of operation, and in-turn stress on the system due to number of switching on the fault. Supervision function will enhance the overall life of the breaker and allow condition based breaker maintenance and limit breaker wear due to reclosing operations.
• The 850R supports single-pole and three-pole reclosing
• Initiation can be via any internal protection elements or external
• 4 reclosing “shots” are supported with separate ‘dead times’ for each shot
• Additonal timer is available to extend the dead timer delay
• The 850R has an option to force three-pole reclosing for single-pole trip mode
• The 850R has an option to skip shot number during Reclose-In-Progress
• The 850R can also be programmed to drive to the last shot as well as reduce the maximum number of shots
Auto-Sectionalizer for Switch ApplicationsThe distribution feeders are equipped with feeder switches (pole-top, pad-mount) that can segment the feeder into electrically isolated sections, and each switch is connected to an 850R relay. Load-break or no-load breaking switches can be controlled using the Auto-Sectionalizing functions that coordinates the actions of the breaker/recloser with the feeder switches. At the end of the switching sequence, the switch remains open, allowing upstream sections to resume normal operation. 850R relays installed over the feeder at reclosers and switches can exchange FDIR/FLISR information over IEC 61850 to deploy distributed automation schemes, improving network reliability.
Pseudo VoltageFor a distribution feeder with only one VT/voltage source (to measure single phase to neutral voltage or phase-to-phase voltage), 850R facilitates 3-phase power and energy measurements derived from pseudo 3-phase voltages. The pseudo 3-phase voltage are derived from any one VT source connected by considering balanced 3-phase system (i.e. all three phase voltages and currents same in magnitude and placed 120o apart with individual phases). Since, the pseudo 3-phase voltage calculation relies on a balanced power system, calculation accuracies are influenced by system unbalance conditions. For a perfectly balanced system, the calculated pseudo voltages match the actual system voltages, however, errors in 3-phase power and energy calculation increases with system unbalance. The generated 3-phase voltages from a single-phase reference input are only used for calculating the 3-phase metering quantities.
VT Terminal InterfaceFreely configurable terminal interfaces match the distribution utilities line transpose conditions, and thus match internal relay protection calculations.

Overhead distribution reliabilityTransient Ground Fault Detection (TGFD)Transient Ground Fault Detection (TGFD) also called Transient Earth Fault Detection (TEFD) is a novel technique to detect the direction of a ground fault in three different grounding systems: ungrounded, resistance grounded and compensated/resonant-ground ( i.e. Petersen coil grounded). The advantage of an ungrounded or compensated ground system is that a most common single phase to ground fault does not cause fault current to flow and therefore the system remains operational to enhance network reliability. As a result, these types of systems make it difficult to detect the fault in the system, and must be designed to withstand high transient and steady state overvoltage. Therefore TGFD is generally applied to limited low and medium voltage (LV/MV) distribution systems.
Broken ConductorThe Broken Conductor detection function will detect a line broken conductor condition or a single-pole breaker malfunction condition through checking the phase current input phasors and the I_2 / I_1 ratio. In normal and balanced load situations this ratio is zero, while in severe load fault conditions an unbalance is produced and this ratio increases. The intention of this function is to detect a single-phase broken conductor only. As such two phase or three-phase broken conductors cannot be detected.
To distinguish between single-phase disappearance and system disturbance in all three phases (such as load change, switching, etc.), the broken conductor element monitors the change in all three phase currents at the present instance and at four cycles previous. It also monitors changes in the I_2 / I_1 ratio, I_1 minimum, and I_1 maximum.
The broken conductor function should not be used to respond to fault transients and single-pole tripping/reclosing conditions. The time delay should therefore be programmed to a sufficient length to ensure coordination with the breaker dead time of the recloser function. The broken conductor pickup flag is asserted, when the I_2 / I_1 ratio of the current bank is above the PKP value, the positive current is in a range of nominal, and phase current changes. The broken conductor Trip flag is asserted if the element stays picked up for the time defined by the pickup time delay. The element instantaneously drops from pickup without operation, if the I_2 / I_1 ratio decreases to 97% to 98% of the pickup value, before the time for operation is reached.
Neutral Admittance (21YN)The 850 successfully detects ground fault in compensated or isolated MV networks based on neutral admittance criteria.
Measured or calculated values of neutral current (I0) and neutral voltage (V0) are used to calculate the shunt neutral admittance (Y0), conductance (G0) and susceptance (B0).
Distributed Resource IntegrationProtection equipment is of considerable importance for secure and reliable operation of networks, connection facilities and generating plants. National grid codes and regulations require that DER units feeding into the MV grid must support the mains voltage of a network failure. Therefore, the purpose of voltage and frequency protection units at machine level is to disconnect the generating units from the grid in case of faults. If the voltage drops and an inductive, reactive power flow in the direction of the generating unit are detected at the network connection point simultaneously, the affected generating unit will be switched off (disconnecting the generator circuit breaker). After an unsuccessful attempt to disconnect the generating unit, the whole DER plant will be switched off by the circuit breaker at the network connection point.
Time Undervoltage (27T)Regional requirements, also referred to as Grid Code compliance, are imposed at point of common coupling (PCC) for the integration of renewables/DERs into the distribution system. For example, in case of a voltage drop, power sources are sometimes required to continue supporting the grid and not be disconnected from the grid, which is referred to as Low-Voltage Ride-Through (LVRT) capability. Therefore, a conventional phase undervoltage protection may not be adequate for such scenarios. The timed undervoltage element can be set as a time dependent element which can be programmed with ten configurable points that make up its characteristics curve. Since every region has its own grid code curve, 850 allows a configurable curve to continue grid support for brief voltage drops and operate for voltage drops. Additionally, the element provides counter-based protection which counts the number of transient voltage drops and trips according to the provided threshold for the given time window. The input voltages are the three phase to phase voltages from delta connected VTs (PTs) or three phase to ground voltages from wye connected VTs (PTs).
850R Recloser Controller

Undervoltage Reactive Power (27Q)National grid codes and regulations require that DER units feeding into the MV grid must support the mains voltage of a network failure. If the voltage drops and an inductive, reactive power flow in the direction of the generating unit are detected at the network connection point simultaneously, the affected generating unit will be switched off (disconnecting the generator).
UV reactive power protection function operates after a settable time delay (programmed as Pickup Delay) as soon as:
• Phase voltages fall below the set voltage level, programmed as Pickup Voltage
• Positive sequence current I1 exceeds the current supervision level
• Reactive power exceeds (Var Direction = Reverse) Pickup, or falls below (when Var Direction = Forward) the Pickup value
With the restoration function, the 850R can send closing command to the generating unit Recloser/CB when:
• Phase voltages are above the minimum voltage level, programmed as Min Voltage, and
• Frequency is within the minimum and maximum range as programmed in the Synchronism Check function
Synchronism CheckThe recloser control includes two synchronism check elements. The function is intended for supervising the paralleling of two parts of . The Synchrocheck elements are typically used at locations where the two power source/generation of the system are interconnected. It is common practice to automatically perform. Synchrocheck function ensures the sources are within allowable voltage, frequency & phase angle limits before permitting closing of the recloser. If this feature is enabled, the check will be performed before either manual close or automatic reclose attempt.
Undercurrent (37)The 850R relay provides three undercurrent element per protection group. The element responds to a per-phase current. An alarm occurs if the magnitude of any phase current falls below the undercurrent alarm pickup level for the time specified by the undercurrent alarm delay. Furthermore, a trip will occur if the magnitude of any phase current falls below the undercurrent trip pickup level for the time specified by the undercurrent trip delay. The alarm and trip pickup levels should be set lower than the lowest feeder loading during normal operations.
Fast UnderfrequencyThe Fast Underfrequency element measures frequency by detecting the consecutive voltage zero crossings and measuring the time between them. The measured frequency has the range between 20 to 70 Hz. The out-of-range measurement will be classified as invalid, which will not affect the behavior of SET and RESET counters. Compared to the regular metered voltage frequency value, the fast frequency has the faster response but lesser accuracy.
Load EncroachmentThe load encroachment element responds to the positive-sequence voltage and current and applies a characteristic shown in the figure below:
The element operates if the positive-sequence voltage is above a set level, and asserts its output signal so that it can be used to block selected protection elements such as phase overcurrent.
Front Panel VisualizationThe User interface is a color LCD front panel display with up to 6 configurable Single Line Diagrams (SLD), 12 control objects, 15 status & 15 metering objects with a provision to control the breakers and switches. Display of online metering and status information is also included.
Support for Recloser and switch control including Hot Line Tag through the single line diagram and 10 user-programmable pushbuttons. 10 user-programmable LEDs are used for indication.

Advanced Monitoring and Diagnostics
Coil Circuit SupervisionThe driving electronics board checks the coil connection continuity of the trip/close circuit, as well as the leakage current to ground. When magnitude of any phase current falls below the undercurrent trip pickup level for the time specified by the undercurrent trip delay. The alarm and trip pickup levels should be set lower than the lowest feeder loading during normal operations.
Capacitor Voltage AlarmThe Capacitor Voltage Alarm function defines the low voltage alarm for the internal/external capacitor charging power supply circuit. This rated voltage is used for charging the external capacitors that open and close the single-pole of the recloser. If the measured voltage of the capacitors is less than the configured percentage of the rated voltage, then the Cap Volt OP operand is generated. In addition, to prevent the charger from damage due to overloading or load short faults created by incorrect wiring, bad capacitors, or hardware failures, the 850R automatically turns off the capacitor charger to prevent damage.
Recloser Wear and Recloser/OHSW Health MonitoringThe 850R relay provides recloser/OHSW health information by monitoring and analyzing the operation count, arcing energy of breaking current, arcing time, opening time, and closing time when applicable. The recloser health status depends on many factors, such as permissible operation number, magnitude of breaking current, mechanical wear and contact wear.
Time of Day TimerThe Time of Day Timer function provides the user with the ability to program control actions based on real time. There are two identical Time of Day Timers.
Application
Monitoring of the total accumulated energy/accumulated demand/minimum and maximum power demand at the end of an event or a shift interval.
A shift can be defined by the breaker status operand (opclosed) or operand derived from the Time of Day Timer element.
Voltage DisturbanceThe Voltage disturbance function of Voltage Swell and Voltage Sag, as described in IEEE 1159-2009. When the voltage on any phase drops below this level a voltage sag condition occurs. Voltage sags are usually associated with system faults but can also be caused by switching heavy loads or starting large motors. Short duration voltage sag may cause process disruptions. Voltage swells are usually associated with system fault conditions, but they are much less common than voltage sags. An SLG fault on the system can cause a swell to occur, resulting in a temporary voltage rise on the healthy phases. Swells can also be caused by switching off a large load, load shedding, or switching on a large capacitor bank. Voltage swell may cause failure of the components depending upon the magnitude and frequency of occurrence.
Battery Monitoring & Testing850R monitors the battery voltage and supports testing the battery when the battery is fully charged and the system is powered by the main power supply. The system tests the battery condition with a predetermined load, at configured test cycle time (typically once in 24 hours).
Quality & ReliabilityIndustry-leading quality, reliability and design processes are at the core of the 850R. Significant investments in state-of-the-art type test facilities simulate a complete and onerous range of operating environments. The 850R is manufactured and designed to the IPC A-610 Class 2 standard, adhering to the highest reliability standards and ensuring rugged performance. Each device completes one hundred percent Electrical Stress screening prior to shipping from GE’s facility.
